by affecting the mortality rate
Migration can affect population distribution by causing the population of one area to increase while simultaneously decreasing the population of another. This can also cause one area to be more densely populated than another.
Adding heat to the object if the object is a solid.
Lack of genetic diversity which may result in destruction of an entire population if there is a change in climatic or environmental conditions; the population does not have a gene pool that may provide some resistant members which could survive
A density-independent factor for a flock of Canada geese on a large lake could be a severe weather event, such as a storm or extreme cold snap. These environmental conditions can impact the geese regardless of their population size, affecting their food availability, shelter, and overall survival. Other examples include habitat destruction or pollution, which similarly do not depend on the density of the geese population.
They could leave because there is not enough food or water. Or there could not be enough space or the weather conditions could be wrong. When their homeland or where they're living is destroyed
they change because people could want a better lifestyle or to increase the population.
One method would be to find the total number of people living in the region divided by the total area of the region. Other methods are just alternatives to this and depend on what you are finding. For example, you could use the total land area, total urban area etc.
More predators so the population would decrease :(
A population is "density-dependent" when it is affected by its size. An example might be population growth: as a population gets large, it might grow slower since there are less resources to use up or diseases become prevalent. The growth rate depends on the population size (also called population density). A population is "density-independent" when the current size doesn't change anything. For example bacteria populations are largely density-independent when they are small. For example they roughly double in size every few minutes. Whether you start with one single bacterium or a colony of 100, the total count will double every few minutes. This is exponential growth. Only after the bacteria colony gets extremely large (millions or billions of individual cells) will the density begin to affect the colonies growth rate, at which point its population growth is then density-dependent. Another example of a density-independent process might be radioactive decay. No matter how much of the radioactive matter is left at any point in time, half of it will be left after one half-life length of time into the future. It does not matter how the material is arranged, it could be one big clump of material (densely packed together), or it could be smashed into many bits separated far away from each other.

Density-independent limiting factors that may prevent human population growth include natural disasters like earthquakes or hurricanes. Density-dependent limiting factors could include limited access to resources such as food and water, which can be exacerbated as the population increases. Additionally, the spread of diseases in crowded areas can also limit human population growth.
